'Law' in the Bible

So she and her daughters-in-law got ready to go back from the country of Moab, for news had come to her in the country of Moab that the Lord, in mercy for his people, had given them food.

And she went out of the place where she was, and her two daughters-in-law with her; and they went on their way to go back to the land of Judah.

And Naomi said to her two daughters-in-law, Go back to your mothers' houses: may the Lord be good to you as you have been good to the dead and to me:

Then again they were weeping; and Orpah gave her mother-in-law a kiss, but Ruth would not be parted from her.

And Naomi said, See, your sister-in-law has gone back to her people and to her gods: go back after your sister-in-law.

So Naomi came back out of the country of Moab, and Ruth the Moabitess, her daughter-in-law, with her; and they came to Beth-lehem in the first days of the grain-cutting.

And Boaz answering said to her, I have had news of everything you have done for your mother-in-law after the death of your husband; how you went away from your father and mother and the land of your birth, and came to a people who are strange to you.

And she took it up and went into the town; and she let her mother-in-law see what she had got, and after taking enough for herself she gave her the rest.

And her mother-in-law said to her, Where did you take up the grain today, and where were you working? May a blessing be on him who gave such attention to you. And she gave her mother-in-law an account of where she had been working, and said, The name of the man with whom I was working today is Boaz.

And Naomi said to her daughter-in-law, May the blessing of the Lord, who has at all times been kind to the living and to the dead, be on him. And Naomi said to her, The man is of our family, one of our near relations.

And Naomi said to Ruth, her daughter-in-law, It is better, my daughter, for you to go out with his servant-girls, so that no danger may come to you in another field.

So she kept near the servant-girls of Boaz to take up the grain till the cutting of the early grain and the cutting of the late grain were ended; and she went on living with her mother-in-law.

And Naomi, her mother-in-law, said to her, My daughter, am I not to get you a resting-place where you may be in comfort?

So she went down to the grain-floor and did all her mother-in-law had said to her.

And when she came back her mother-in-law said to her, How did it go with you, my daughter? And she gave her an account of all the man had done to her.

And she said, He gave me these six measures of grain, saying, Do not go back to your mother-in-law with nothing in your hands.

He will be a giver of new life to you, and your comforter when you are old, for your daughter-in-law, who, in her love for you, is better than seven sons, has given birth to him.
